Keyboard navigation has been made easier. Shortcuts for the main actions have been implemented (look at the underlined chars). Also experiment with TAB, arrows, PGUP, PGDOWN, and SPACE or ENTER to select things.

sourceinstall own configure script is now able to detect a wider range of problems, and now reports package versions.

Interpreter detection can be left to ./configure (first attempt is tclsh, second choice is expectk), or it can be overridden using the --with-tclsh[=NAME] or --with-expectk[=NAME] options.
